Patented Feb. 18, 1930 UNITED STATES JOHN BRANDWOOD, F SOUTI-IPORT,ENGLAND YARN BEAM Application filed January 15, 1926. Serial No. 81,561.

The treatment with dye or analogous liquors of yarns wound on beams bythe passing of the said liquors through the yarns and through the bodyof the beam has great and commercially recognized advantages as tosaving of time and cost, over the old method of skein dyeing analogoustreatment; and also, when there is a suih'ciency of the yarn to be dyed,over the method of dyeing the yarn in cheeses or like packages and thenwinding upon a beam for subsequent handling. it often happens howeverthat the quantity of yarn to be dealt with is not suflicient to fill atreatment beam of full size and is too great for economical handling bythe cheese treatment methods. Skein dyeing is then resorted to, with theunavoidable disadvantage of the extra costs, entailed by that methodover the beam treatment method.

The object of this present invention is to provide means whereby yarn inquantities less than that required to fill an ordinary full sized beam,for treatment thereon, may be wound as required and then dyed orotherwise treated in the same manner and by the same means as a fullsize beam. According to the said invention section beams are employed toany desirable number and of any desired width between flanges, withmeans for assembling a plurality of such section beams into a completebeam, and means ior ensuring that all fluids with which the yarns on thesaid section beams are to be treated shall pass through the yarns onlyin the treatment vessel.

A very convenient method of carrying the invention into effect willnow'be described, it being understood that the details given may bevaried without departing from the spirit of the invention.

In the drawings Figure 1 is an end elevation of a section beam showingthe flange and a method of securing one type of yarn bearing surfacewithin the end flanges;

Figure 5 is an elevation, partly in section of a full size beam composedof a plurality of section beams of varying widths; Figure 6 is anelevation (broken) partly in section section of a filler or dummy beam;and

Figure 7 is an elevation of an assembled beam consisting of a pluralityof section beams one of which is a dummy section beam.

Referring to Figures 1 and 2, 6 are end flanges each of which as to itsouter portionis composed of non-corrodible metal of convenientthickness, nickelor a nickel alloy may be used. The inner portion ofeach flange is composed of a ring of cast metal 7 having thestrengthening arms 8, the central bore 9 for the reception of a shaft,circular bosses 1O bored for the reception of further shafts. The edgeor" each ring is returned outwardly as at 11, thus forming an anglering, and the outer peripheries of the rings so formed are slotted on aradius as at 12. Each slot 12 is of just sutficient width to allow of astrip of non-corrodible metal 13 to be pushed thereinto with a tightpush fit. Intermediate of the end flanges is the supporting ring 14which is slotted in a similar manner to the flange rings 7 to receivethe metal strips 13. The supporting ring 14: is provided with the bosses15' registering with the similar bosses 10 of the flange rings 7, andthrough these bosses on the flange rings and intermediate supportingring are passed tubular shafts 16, which are threaded at theirextremities to receive nuts 17. The ring 14 may be maintained in theposition longitudinally of the beam in any convenient manner, forinstance by means of set screws passing through bosses and engaging thetubular shatts. The outer flange portions 6 of nickel or the like, whichare annular, have their inner peripheries returned as at 18, and theangle rings 7 are secured within these returned flanges 18 by the rivets19.

It is essential, to ensure that when two sections are in place together,there should be no passage for fluids between adjacent flanges, astreatment by fluids under pressure is contemplated and all fluids mustpass through the yarns only to the interior of the beam, or in thereverse direction, in the known manner of treating full sized beams ofyarn. A convenient method of making a fluid tight joint is shown inFigure 3. One angle ring 7 of each section has the inner face of itsperipheral flange 11 recessed as shown at 20, and the other angle ring 7is recessed on the outer face of the peripheral flange as shown at 21.lVhen two section beams are placed together, therefore, a rabbet jointis formed which, the recesses being machined and faced up, will underpressure form a fluid tight joint.

Various sect-ion beams sufficient to form a complete beam length havingbeen wound, these section beams-five various widths are shown in Figure5are taken and a central shaft 22 Figure 5 is passed through the centralbosses 9. Rods 23 of a non-corrodible metal such as Monel metal, arethen passed through the tubular shafts 16 of the section beams, theserods being threaded at their extremities to receive the nuts 24, as seenin Figure 4. In this figure the metal strips 13 are omitted forclearness. By screwing up the nuts 24 therefore the adjacent flanges ofsection beams are pressed tightly together and the plurality of'sectionbeams are for practical purposes transformed into a singi beam forhandling and treatment in a treatment vessel, such as the kier describedin the specification to United States Letters PatentNo. 1,174,662. Itwill be noted that owing to the form of the flange rings 7 the endflanges of the completed composite beam will always have a tubular bossto fit within a seating of a vessel such as that described in the priorspecification just referred to, whilst it may be maintained in positionby the screw also described in that specification, the central shaft 22of course being removed.

The weight of yarn on each section beam is of course much less than theweight of yarn wound on a complete single unit full size beam, and it isconsidered unnecessary there fore to provide a strong cast iron or likebacking for the nickel or like flange portions. Nevertheless where it isthought desirable such backings may be provided, as they will not comeinto contact with the yarns. Where the nickel or like outer flangeportion only is employed, the periphery of such flange may be turnedover as shown at 25 Figure 4, to present a greater surface for supportof the edge when it is for instane rolled, to prevent distortion of theplane of the flange.

The section beams which go to form a complete composite beam need not beof equal widths between flanges. They may be of varying widths toreceive a greater or smaller weight of yarn, as in Figure 5. Any overallwidths or combination thereof, suitable to make up the length of a fullsized beam may be adapted. here the length of a section beam makes itdesirable, extra supporting rings may be provided between the flanges orthe ring may be omitted. Two of these are shown in the section beam onthe right of Figure 5; the next in position has one; whilst theremaining two sections being comparatively narrow, do not require theseintermediate supports.

Any convenient and suitable means for winding section beams for thepurpose of the invention may be employed, for instance the knownsectional warping frame or the ordinary full beam warper. If the latteris employed the usual winding drum is removed and winding effected bymeans of the apparatus described in the specification of application forUnited States patent filed under Serial No. 32,513. By the latter methoda number of sections may be wound simultaneously, when connectedtogether. At those points where flanges and angle rings occur in thelength of such a composite beam, the dents in the comb of the warpingframe which are opposite to the said flanges and rings are of courseleft blank.

After treatment of the yarns, the composite beam may be handled in anydesired manner, or the said beam disassembled for the handling of eachsection beam separately.

It is not-essential for the purposes of this invention that the yarnbearing surface of a section beam should be formed of strips of metal asshown in Figures 1, 2 and 5. The construction of a beam such asdescribed in the specification to United States Letters Patent No.1,125,803 may of course be followed, with the necessary modificationwhere necessary as to the structure of the flanges.

In addition to the advantage of enabling various section beams to bewound with a less number of ends of yarn upon each than would benecessary to fill a full beam, with subsequent treatment of .a pluralityof such section beams together, the invention can be employed for thepurpose of treating a number of section beams which, in their totallength when placed together as hereinbefore described, would fall shortof the length of a complete and single unit beam. WVhere the number ofsection beams wound with yarn is not sufiicient to form, when suchsection beams are placed together, a complete beam of a sufficientlength for treatment in a desired vessel as for instance the kier ofUnited States Letters Patent 1,174,662, fillers or dummy sections may beemployed to make up the necessary length, and a convenient form of sucha filler or dummy is illustrated in Figure 6. In that figure, 26 is anangle ring which with the exception of the radial slots 12 may be of thesame form and construction as the angle rings hereinbefore described andindicated at 7 in the drawings Figures 1, 2, 3 and l. The surface of thedummy beam is composed of an imperforate cylinder 27 of metal open atthe ends and riveted to the angle rings as shown in Figure 6. Theflanges 6 are omitted as being unnecessary but as shown in the Figure 6the means for making a tight joint with an adjacent section beam flangeare provided on the angle rings. The position of one such dummy sectionin its relation to the yarn bearing section beams, in a completeassembled beam, is shown in Figure 7.

By using more of these fillers therefore as may be required or only oneof the length required the full length of a complete beam may be made upfor treatment, whilst the imperforate surface of the cylinder 27effectually prevents the passage of fluids other than through the yarnson the adjacent section beams when a filler or fillers is or areassembled with such section beams.

In the form of dummy beam illustrated tubular shafts 16 are provided asin the section beams for the passage of the tie rods 23 therethrough.
